Simón Bolívar triumphs over Spain in the Battle of Boyacá.

The Battle of Boyac (1819), was the decisive battle that ensured the success of Bolvar's campaign to liberate New Granada. The battle of Boyaca is considered the beginning of the independence of the north of South America, and is considered important because it led to the victories of the battle of Carabobo in Venezuela, Pichincha in Ecuador, and Junn and Ayacucho in Peru.New Granada acquired its definitive independence from the Spanish Monarchy, although fighting with royalist forces would continue for years.:232235Brigadier Generals Francisco de Paula Santander and Jos Antonio Anzotegui led a combined republican army of Newgranadians to defeat in two hours a Royalist Newgranadian forces led by Spanish Colonels Jos Mara Barreiro and Francisco Jimnez.

The battle occurred 150 km from Bogot in the Andes Mountains, in a place known as Casa de Teja, close to a bridge over the Teatinos River and 3 roads heading to Samaca, Motavita and Tunja, an area which is now part of the Boyac Department.

Simón José Antonio de la Santísima Trinidad Bolívar y Ponte Palacios y Blanco (English: BOL-iv-ər, -⁠ar, also US: BOH-liv-ar, Spanish: [siˈmom boˈliβaɾ] (listen); 24 July 1783 – 17 December 1830), also colloquially as El Libertador, or Liberator of America, was a Venezuelan military and political leader who led what are currently the countries of Colombia, Venezuela, Ecuador, Panama, Peru, and Bolivia to independence from the Spanish Empire.

Bolívar was born in Caracas into a wealthy family and, as was common for heirs of upper-class families in his day, was sent to be educated abroad at a young age, arriving in Spain when he was 16 and later moving to France. While in Europe he was introduced to the ideas of the Enlightenment, which later motivated him to overthrow the reigning Spanish in colonial South America. Taking advantage of the disorder in Spain prompted by the Peninsular War, Bolívar began his campaign for independence in 1808. The campaign for the independence of Colombia (Gran Colombia—later New Granada) was consolidated with the victory at the Battle of Boyacá on 7 August 1819. He established an organized national congress within three years. Despite a number of hindrances, including the arrival of an unprecedentedly large Spanish expeditionary force, the revolutionaries eventually prevailed, culminating in the victory at the Battle of Carabobo in 1821, which effectively made Venezuela an independent country.

Following this triumph over the Spanish monarchy, Bolívar participated in the foundation of the first union of independent nations in Latin America, Gran Colombia, of which he was president from 1819 to 1830. Through further military campaigns, he ousted Spanish rulers from Ecuador, Peru, and Bolivia, the last of which was named after him. He was simultaneously president of Gran Colombia (present-day Venezuela, Colombia, Panama and Ecuador), Peru, and Bolivia, but soon after, his second-in-command, Antonio José de Sucre, was appointed president of Bolivia. Bolívar aimed at a strong and united Spanish America able to cope not only with the threats emanating from Spain and the European Holy Alliance but also with the emerging power of the United States. At the peak of his power, Bolívar ruled over a vast territory from the Argentine border to the Caribbean Sea.

Bolívar is viewed as a national icon in much of modern South America, and is considered one of the great heroes of the Hispanic independence movements of the early 19th century, along with José de San Martín, Francisco de Miranda and others. Towards the end of his life, Bolívar despaired of the situation in his native region, with the famous quote "all who served the revolution have plowed the sea".: 450  In an address to the Constituent Congress of the Republic of Colombia, Bolívar stated "Fellow citizens! I blush to say this: Independence is the only benefit we have acquired, to the detriment of all the rest."
